Is there way to configure AP failover between two stand alone Master Controllers ?
If they are standalone masters, how would their configuration be synchronized?
Thanks Colin we tested the same and working.only Concern is if the Primary LMS IP not reachable and AP goes to Backup LMS IP and working fine. When AP associated with backup LMS IP and at this moment if AP reboots for any reason and Primary LMS IP is still unreachable AP is not coming UP as Master IP is Primary LMS IP.
Hope this is normal and there is no way we can avoid?
In that case, the master discovery mechanism needs to be fool proof if the AP reboots.
You can use one of the following methods:
1. Master discovery can be set to use ADP (Aruba discovery protocol) .(provided ADP broadcast or multicast packets can reach the controllers)
2. Use DNS based mechanism for master discovery.
We can add a DNS record for aruba-master & add IP addresses of both the controllers.
So, when AP will discover the master via DNS, it will be presented with two IP's. It will try to reach the first IP & if that is unreahcable it will try for the 2nd one.
thanks for solution . fortunately we did discuss the same.
